Definitions

  • the invention is in the field of solid detergents and relates to a new one Process for the production of solid, water-free detergent granules based on Sugar surfactants.
  • Alkyl oligoglucosides are important detergent surfactants because they are non-ionic compounds are compatible with a variety of other ingredients, however one Foaming and cleaning ability show which much more than that of anionic surfactants like.
  • glucose and fatty alcohol are used, which are present acid catalysts are acetalized.
  • the fatty alcohol is usually used in a substantial excess, which has the consequence that the resulting glucosides subsequently with high technical Expense of unreacted alcohol must be freed before it is then aqueous Pastes go on sale.
  • solid detergents before All of extrudates, heavy powders and, more recently, for tablets, become alkyl oligoglucosides however increasingly desired in fixed forms of supply.
  • the object of the present invention was therefore to provide a process for the preparation of water-free detergent granules with a high content of alk (en) yl-oligoglycosides which is free from the disadvantages described, ie at the earliest possible point in the production the glycosides are attached, thus minimizing the technical effort and the manufacturing costs for the granules.
  • the invention relates to a process for the production of anhydrous detergent granules, in which one mixes technical mixtures of alkyl and / or alkenyl oligoglycosides and fatty alcohols reduced to a residual fatty alcohol content of a maximum of 30% by weight, and the resulting melt in a mixer or extruder with detergent additives mixed.
  • Alkyl and alkenyl oligoglycosides are known nonionic surfactants which follow the formula (I) R 1 O- [G] p (I)
  • R 1 is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms
  • G is a sugar radical having 5 or 6 carbon atoms
  • p is a number from 1 to 10.
  • the alkyl and / or alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
  • the preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglycosides .
  • the index number p in the general formula (I) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10.
  • Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, preference is given to those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and is in particular between 1.2 and 1.4.
  • the alkyl or alkenyl radical R 1 can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capronic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis.
  • the alkyl or alkenyl radical R 1 can also be derived from primary alcohols having 12 to 22, preferably 12 to 18, carbon atoms.
  • Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures, which can be obtained as described above.
  • Alkyl oligoglucosides based on hardened C 12/14 coconut alcohol with a DP of 1 to 3 are preferred.
  • Fatty alcohols are primary aliphatic alcohols of the formula (II) R 2 OH (II)
  • R 2 represents an aliphatic, linear or branched hydrocarbon radical having 6 to 22 carbon atoms and 0 and / or 1, 2 or 3 double bonds.
  • Typical examples are capronic alcohol, caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, linolenyl alcohol, linolyl alcohol, linoleyl alcohol, linoleyl alcohol Technical mixtures which are obtained, for example, in the high-pressure hydrogenation of technical methyl esters based on fats and oils or aldehydes from Roelen's oxosynthesis and as a monomer fraction in the dimerization of unsaturated fatty alcohols.
  • fatty alcohol Since the fatty alcohol does not contribute to the washing result, it is desirable for economic reasons to keep its content as low as possible. However, a very low fatty alcohol content means a high energy input for the evaporation, which would then put an economic burden on the process. Furthermore, one has to take into account that the glycosides are sensitive to temperature, so a gentle and therefore technically complex separation would be necessary. Conversely, a higher fatty alcohol content offers a certain economic advantage because the separation can be carried out with less effort. However, this parameter is again limited by the fact that most detergent formulations do not tolerate surfactant granules with a fatty alcohol content above 30% by weight; Higher alcohol levels also destabilize the granules.
  • the depletion of fatty alcohol from the technical mixtures always represents a compromise between the parameters mentioned.
  • the actual depletion is less critical from a technical point of view, i.e. taking into account the known low temperature resistance of sugar surfactants (risk of caramelization), all types of evaporators are considered that take this into account, but preferably thin-film evaporators, falling film evaporators or short-path evaporators and - if necessary - any combination of these components.
  • the depletion can then take place in a manner known per se, for example at temperatures in the range from 110 to 160 ° C. and reduced pressures from 0.1 to 10 mbar.
  • the depleted glycoside-fatty alcohol mixtures are used to produce the detergent granules immediately after leaving the evaporator, i.e. still in melted Condition with typical detergent additives where it are, for example, builders, co-builders, oil and fat-dissolving substances, bleaches, Bleach activators, enzymes, enzyme stabilizers, graying inhibitors, optical Brighteners, polymers, defoamers, disintegrants, fragrances and / or inorganic salts can act.

  • the zeolite can be used as a spray-dried powder or as an undried stabilized suspension that is still moist from its production.
  • the zeolite in the event that the zeolite is used as a suspension, it can contain minor additions of nonionic surfactants as stabilizers, for example 1 to 3% by weight, based on zeolite, of ethoxylated C 12 -C 18 fatty alcohols with 2 to 5 ethylene oxide groups , C 12 -C 14 fatty alcohols with 4 to 5 ethylene oxide groups or ethoxylated isotridecanols.
